Abstract

The invention relates to a method for determining the thickness of a web of continuous material, in which contactless optical methods are used, and measuring takes place with optical spectra, preferably in the infrared (IR) range. In accordance with the invention, continuous spectra are evaluated by chemometric methods and/or neuronal networks, from which the thickness of the material web is advantageously determined by using training sets. An appropriate device for carrying out the method is characterized by a spectrometer (1) having at least one light source, means (10, 10', ...) for transferring the light to the material web (100) and devices (30, 31, 31') for measuring the light intensity after transmission through the material web (100) and for subsequent evaluation in order to determine the material thickness.
